I bought my dad this and borrow it quite a bit.
I plan on playing Integral sometime soon but need a new memory card and I want to get Twin Snakes anyways.
Substance is fun, even though Raiden=meh it is a good game.
Subsistence=FREAKIN' EPIC YO!
From the fact it is MGS3 and the fact it has third person, it is epic.
Couldn't find all those dumb kerotans even with the GA-KO camo so I just beat the whole game without getting alert status. :s
